Subframe processing method and device

Abstract

A subframe processing method and device are disclosed. A terminal can determine a special subframe in a non-contiguous secondary carrier according to a maximum continuous channel occupancy duration and a channel listening duration of the non-contiguous secondary carrier, and a channel occupancy start reference time point and/or a channel listening start reference time point of the non-contiguous secondary carrier that are obtained, where the special subframe includes all or some gap symbols occupied by the channel listening duration, use all symbols except the gap symbols in the special subframe as symbols that can be occupied by a PDCCH and/or a PDSCH, and correspondingly receive or decode the PDCCH and/or the PDSCH in the special subframe according to the symbols that can be occupied by the PDCCH and/or the PDSCH.

What is claimed is: 
     
       1. An apparatus, comprising:
 a processor; and 
 a non-transitory storage medium including executable instructions, wherein the executable instructions include instructions for:
 receiving configuration information of a first carrier from a network device, wherein the configuration information indicates whether the first carrier comprises a common channel; 
 determining, according to the configuration information, whether the first carrier comprises the common channel; and 
 receiving or decoding a physical downlink shared channel (PDSCH) carried in the first carrier according to the following:
 in response to determining that the first carrier comprises the common channel, and when receiving or decoding the PDSCH carried in the first carrier, excluding, from symbols allocated to be occupied by the PDSCH, symbols allocated to be occupied by the common channel; or 
 in response to determining that the first carrier does not comprise the common channel, and when receiving or decoding the PDSCH carried in the first carrier, skipping excluding, from symbols allocated to be occupied by the PDSCH, symbols allocated to be occupied by the common channel. 
 
 
 
     
     
       2. The apparatus according to  claim 1 , wherein the common channel is a common broadcast channel. 
     
     
       3. The apparatus according to  claim 1 , wherein the common channel is a common synchronization channel. 
     
     
       4. The apparatus according to  claim 1 , wherein the common channel is used to transmit a synchronization signal. 
     
     
       5. The apparatus according to  claim 1 , wherein the common channel comprises a physical broadcast channel (PBCH), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS). 
     
     
       6. The apparatus according to  claim 5 , wherein the common channel further comprises a reference signal. 
     
     
       7. A method, comprising:
 receiving, by a terminal, configuration information of a first carrier from a network device, wherein the configuration information indicates whether the first carrier comprises a common channel; 
 determining, according to the configuration information, whether the first carrier comprises the common channel; and 
 receiving or decoding a physical downlink shared channel (PDSCH) carried in the first carrier according to the following:
 in response to determining that the first carrier comprises the common channel, and when receiving or decoding the PDSCH carried in the first carrier, excluding, from symbols allocated to be occupied by the PDSCH, symbols allocated to be occupied by the common channel; or 
 in response to determining that the first carrier does not comprise the common channel, and when receiving or decoding the PDSCH carried in the first carrier, skipping excluding, from symbols that are allocated to be occupied by the PDSCH, symbols allocated to be occupied by the common channel. 
 
 
     
     
       8. The method according to  claim 7 , wherein the common channel is a common broadcast channel. 
     
     
       9. The method according to  claim 7 , wherein the common channel is a common synchronization channel. 
     
     
       10. The method according to  claim 7 , wherein the common channel is used to transmit a synchronization signal. 
     
     
       11. The method according to  claim 7 , wherein the common channel comprises a physical broadcast channel (PBCH), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS). 
     
     
       12. The method according to  11 , wherein the common channel further comprises a reference signal. 
     
     
       13. A non-transitory computer-readable storage medium, comprising executable instructions for execution by a computer, wherein the executable instructions comprise instructions for:
 receiving configuration information of a first carrier from a network device, wherein the configuration information indicates whether the first carrier comprises a common channel; 
 determining, according to the configuration information, whether the first carrier comprises the common channel; and 
 receiving or decoding a physical downlink shared channel (PDSCH) carried in the first carrier according to the following:
 in response to determining that the first carrier comprises the common channel, and when receiving or decoding the PDSCH carried in the first carrier, excluding, from symbols allocated to be occupied by the PDSCH, symbols allocated to be occupied by the common channel; or 
 in response to determining that the first carrier does not comprise the common channel, and when receiving or decoding the PDSCH carried in the first carrier, skipping excluding, from symbols that are allocated to be occupied by the PDSCH, symbols allocated to be occupied by the common channel. 
 
 
     
     
       14. The non-transitory computer-readable storage medium according to  claim 13 , wherein the common channel is a common broadcast channel. 
     
     
       15. The non-transitory computer-readable storage medium according to  claim 13 , wherein the common channel is a common synchronization channel. 
     
     
       16. The non-transitory computer-readable storage medium according to  claim 13 , wherein the common channel is used to transmit a synchronization signal. 
     
     
       17. The non-transitory computer-readable storage medium according to  claim 13 , wherein the common channel comprises a physical broadcast channel (PBCH), a primary synchronization signal (PSS), and a secondary synchronization signal (SSS). 
     
     
       18. The non-transitory computer-readable storage medium according to  claim 17 , wherein the common channel further comprises a reference signal.
